And LONGITUDE of ABERDEEN, i6i 



believe that 8' 32" or 2° 8' is not far from the exadl longitude 

 of this place. Hence the latitude of the Girdlenefs is 57° 8', 

 and longitude 2° 6' W. and the latitude of Greigfnefs 57** 7' 20'''', 

 and longitude 2° 6' W. alfo. 



The latitude and longitude of Aberdeen, as determined above, 

 differ confiderably from the fame as given in moft books of 

 geography and navigation, where indeed they are ufually ftated 

 with great inaccuracy. Mr Downie, to whom, at hi& requeft, 

 I communicated the refult of my obfervations, has, in his New 

 Pilot f placed Aberdeen nearly as above, and of courfe has laid 

 down the adjacent coaft, with much more precifion than had 

 been formerly done. This was in 1793 ; I then fuppofed the 

 longitude 2° 9' W. which is i' greater than the above determL- 

 nation.
